That's a pretty decent amount of money, so you should be good. As is true with most effects pedals, remember that the less expensive effects stations (big pedals with 4 pedals, a wah wah pedal, the ability to edit and store effects, etc.) can be a good thing if a reliable version is bought. They tend to be less user friendly, but can open up your ears and give you tons of options. Still, if you find a sound or two you really like, I would suggest getting a solitary pedal for the sound. You don't have as much creative freedom, but you have better quality in both a recording and playing aspect. The more expensive high end effect station type pedals do a great job of offering you the freedom with sound quality, but those pedals usually cost more than the amp, and are higher than your budget.

And though this isn't entirely relavent, they have a pedal out that changes the tune of your instrument through the amp without actually having to tune the instrument. Called an up-tuner/down-tuner or something like that. They sound muddy and terrible, as they are taking the sound input and changing the tuning digitally. There is clicking, feedback, and the playing is even more sensitive as the waves are altered to make a different sound. It seems like it would be a fun idea to practice songs without changing tunes, but I don't want you, or anyone else, to make that mistake, heh.

All the best!
