I am lookin to buy a zoom g2 1u or a boss me 20 but i cant work out which one to choose...

i was wondering if any one has any info on them and and which one is best for a beginner on a tight budget..

Look at E bay maybr you could pick up a Boss me-50 for cheap, i'd advise you try both out in your local shop not a big fan of Zoom,
Agreed, you'll be better off with a Boss ME-50 than an ME-20.. You won't find yourself in need of better effects very soon with the ME-50!

Either way, Boss over Zoom any day.
Don't buy the Zoom. I have one, but don't use it anymore. The amp models suck.
The effects are ok, but not superb.
Fender MIA Stratocaster (with SD Twang Banger)
Epiphone Les Paul Special II
Johnson Acoustic
Palmer FAB5
I'd just go ahead and buy it new and not be one of the many ebay horror stories on here.
