In that case, what should I build? As you can probably tell, I don't have a whole lot of experience in dealing with 3d printer design, so I'd like to know what I should do? My goal would be to make something for under $250. I mainly liked the Wallace because of the frame design, but if you have something in better in mind, please tell me.

A lot of people say "I'll get this cheapo kit and as I learn about its problems I'll fix the things that are wrong with it". The problem with that idea is that the cheapo kit can't be converted to a good machine by replacing parts one by one any more than a Yugo can be turned into a Ferrari by replacing parts one by one. It is so fundamentally flawed that there is almost nothing in the kit that will be reusable to build a quality machine. It will be $300 flushed down the toilet. Why not skip that step and save yourself the trouble and expense and go right to the good version of the machine? $300 will buy some high quality parts.

The mechanical stuff isn't rocket science. Take the frame design for example. There's one simple rule of thumb that will allow you to make a better frame than 99% of kits: if you push on it and you can see it move, it isn't rigid enough. That's as complicated as it gets. If you can accept this principle but don't know where to go from there, look at some quality machines and ask questions here. Don't ask "which printer should I buy?", ask "how do I build a rigid frame?".

You know more than you think you do, you just have to learn to apply it. THAT is education that is very worthwhile because it will serve you over and over again.

However, just as you can use a Yugo to get the parts of your Ferrari together, you can use a cheapo printer to make the parts of a good one. And, whilst a Ferrari is necessary sometimes, for a lot of the time you can get by with a Yugo.
The analogy also isn't fair in another sense... 3D printing today is like motoring in the 1900s... back then, if you owned a car, you either needed to be a mechanic, or employ a mechanic/chauffeur. There were no Ferraris back then! Or like owning a computer in the 1970s/80s.
The other problem is how to know if what you're about to buy is a high quality machine, or just a high-priced piece of junk.

Again, this is over-simplifying. All design is compromise. I could build a really rigid frame out of granite, but it would never be a good printer. The really interesting question is "How rigid, light, fast, big, functional a printer can I make for my money?"
