Hi,
There are several of these for sale on Ebay.
There is a used Dremel at $66 with 6 days to go. I expect it may reach $100 by sale time.
There is one by Chicago Electric at $39 and several copies for less.
Harbor Freight has the Chicago Electric for $49.

Does anyone have any experience with any of these saws?
What are their limitations?

Thanks,

Get your self a three wheel band saw. It's a lot more useful for model work. One cavete though. The 3 wheel saws are harder on blades than the 2 wheel models but for model use I'd still go for a three. Harbor Frt. has one that sells for $100. when on sale in store.Ruben

IMHO, the Dremel is the single most useful tool an RC modeler can have -- next to a box of single edge razors and a sanding bar. I paid $59 for my Dremel tool set at Home Depot and could not have built my EIII without it. Between sanding, cutting, drilling, and grinding I don't think I went without using it one single time at the bench! Get one if you are seriously into building. Get TWO if you plan to go into scale building!

By all means get the 4” table saw. I have built models for years, and I have a band saw, a jig saw and a full size 10” table saw. Several years ago a modeling friend sold me a little Dremel 4” table saw and I now consider it one of my basic tools. It’s true the other saws will do most anything that it will do but the difference is accuracy. With a little care, the little 4” saw will produce a part ready to glue in place with no sanding, trimming, or fitting. It will rip basswood, balsa, and even oak into strips of sizes that would be difficult and dangerous on a larger saw. It fills an important role that no other tool can fill.

If you can only afford one power tool (besides a Dremel) get a scroll saw (jig saw). It is quite versitile and can handle the majority of your modeling needs.
