I'm about to take the plunge into 3D printing

Is it better to buy cheap unit first to get feel my way around? Or, buy near top and get all capability budget will allow?

My use will be strictly hobbyist making things for RC flying for myself and maybe friends. Budget is probably $700 or a little more

Don't want to throw away money on very low end printer unless there is some education value.

I'll probably stay in the PLA area with some potential for nylon in future.

Appreciate any tips along these lines.
