mini: Like, you know the mini ones that you get at RadioShack? What's the cheapest one I can get and how much is it? If you don't know the price, how much do they usually cost? And if you don't know that, (I'm asking so much here) then can you help me with this problem: I have a Wilson Ross WR - 54488 and one of the keys is broken kinda, do you know how to fix it? Please help, and thanks for your answers.How much does a mini musical keyboard cost at the least?i got a 68 key keyboard from toys r us for about 200 and that was the most expensive one there.
