In reply to lewmul:
I'm climbing in Tarantulace and I wouldn't describe them as a "cheap, beginner" shoe. From my experience they should be fine until you get to the more serious grades.
I can't see why I can't use small footholds or develop my footwork in them.
There is quite a lot on line in praise of the Tarantulace, especially as being a bit of a bargain.
I would associate "floppy" shoes with "ill-fitting" shoes. For example, I didn't like the La Sportiva Mythos. But, that's down to fit as I've seen someone solo a very hard route in them.
My advice to the OP is to go with fit and feel. But, unfortunately, you can never really tell until you've climbed a bit in them and got used to a new shoe. From that point of view it's not a good idea to splash out on an expensive pair unless you're sure about them.
In any case, I wouldn't trust your advice to avoid inexpensive shoes on the grounds that they are fundamentally inadequate.
