The title pretty much sums it up. I'm in a 3-piece band, and we mostly play cheesy 80's pop/rock. Some of the solos I take are approximations of keyboard/sax solos on the originals, and I'm toying with the idea of an octave pedal to thicken up the sound and add a slight 'keyboard' quality to them.

What do you guys think? Who uses one regularly and what are the best options out there?

As usual I'll be on a tight budget and would probably end up buying from eBay.
