guitar players,help!boss rv3 or rv5?

[discouraged1]

hi all,

i need some help from guitar players from around here.

i am willing to buy a Boss Rv-3 Reverb/Delay pedal for some time, but i have no luck in finding it, it is out of stock(out of producing), and i don't know if its follow-up, Boss Rv-5, is any good(better or worse, and why, if so?).

i need some answers, opinions, but as soon as possible(if possible).

Should I go for a rv-5 or wait to find 2nd-hand rv-3 or something?

Help!

thanx

Moreover,

does any1 know a place where Boss Rv-3 can be found? Online? Anywhere?
thanx.
