I bought that same Craftsman band saw (#21400) a few weeks ago on sale for about $165 + tax. Of course, I had/have fantasies of stumbling upon an incredible Craigslist deal on a decent, classic, American cast iron fixer-upper for a couple hundred dollars, but I finally decided I needed to just get something now so I can slice up stuff.... now. My experience with this band saw obviously is limited, but thus far my impression is that this saw is a great value, and I'm very glad I bought it. If/when I get a "real" band saw, I'll likely keep this small one set up for a dedicated purpose. It appears to be well made of good quality materials, very little plastic, and far superior to any other band saw in the 9" or 10" category I've looked at (other than Rikon). I immediately replaced the stock blade with some recommended blades from Iturra Design, took my time aligning the cast iron table, and reinstalled the upper guide bearing support assembly with a shim so it remains parallel to the blade as it is raised and lowered. I'll probably also eventually replace the blade guide bearings with better bearings with rubber seals (they're a common size, inexpensive skate bearing).
If you Google around regarding Craftsman 10" band saws (bandsaws?), it's apparent that there are a couple of older Craftsman 10" models that folks weren't too pleased to have owned. Reviews of the Craftsman 21400 however are generally favorable, especially if you disregard reviews complaining about Sears stores not stocking the 70 1/2" blade for this saw. The Craftsman 21400 appears to be very, very similar to and have the same specs as the Rikon #10-305 10" band saw (not to be confused with Rikon's older 10" model, the #10-300), and I think the Craftsman #21400 is made by Rikon's sister company in China. The Craftsman and the Rikon band saws both appear to be manufactured by Richen Enterprises, an American-Chinese manufacturing venture (Riley & Chen) founded by the same Erin Riley who founded Rikon, but who apparently is no longer associated with either company. The differences I noted between the Craftsman 21400 and the Rikon 10-305 were the colors of the painted steel panels and the plastic knobs, and the Craftsman saw includes a cheap miter gauge. Rikon's (different, still cheap) miter gauge is sold separately for ~ $15. The Rikon model comes with a 5 year warranty, but even if I had spent another $50 to extend the Craftsman warranty an additional 4 years (I did not, will not), the price difference is still significant. I remember when "Craftsman" was a well-respected brand among craftsmen, but truthfully, today I'd prefer to have a Rikon nameplate rather than a Craftsman nameplate riveted to my band saw, and the Rikon paint is nicer, IMO. In this case however, I opted for the Craftsman "equivalent", and used the savings to buy some quality Starrett, Lenox, and "BladeRunner" blades and a Bevel Boss from Louis Iturra, plus a stand from Harbor Freight.
I used a Crapsman 12" for years and suffered for years. I tried to have it cover all my bases, bowls, HF's, Peppermill blanks, resawing pen blanks...it failed at just about everything and I settled for it. November of last year, I'd saved enough to get a new Jet 1642, Saved enough on Amazon's sale that I was able to get a Grizzly 0555. That with a Woodslicer blade, It does everything I need now and in the future. See if there are other options to meet your needs.
