I just ordered a Colorfly CT132 Q.Tiny 13.3 Inch Tablet from GHdeal.com. Their price is $259. This is considerably less than Amazon and others I found.

Well, it would be cheaper, because they are a Hong Kong based company and they are not charging you for import duties. You might, quite possibly, get away with it, but if Customs realise what is in the box, you could be in for a nasty surprise.

I considered a similar deal, but went with Amazon, as the price was a known quantity and I would also have a more powerful organisation, with some clout, in the event of anything going wrong (which, to be fair, hasn't happened).

Next will be deciding what kind of footswitch to use.

Personally, I would recommend a wired USB pedal. I see little point in using any sort of wireless connection, as there's not a lot of cabling involved, it's a lot cheaper to implement and it's one less thing to screw you up during a performance.
