zoom G3 or G5 are very good for the money. Delays and modulations on them are excellent. sold mine as I only ever use a bit of delay and a phaser. I liked the look of the smaller zoom ms50g but i think that it might be a bit fiddly to use in comparison to the G3/G5. The nova TC repeater is the best delay I've ever had and I've had a few... (tc flashback, mxr carbon copy, Guyatone MD3, echohead, Digitech DL8, boss dd7, tonerider ad3 plus others i';ve forgotten i owned!). Never noticed any tonesuck from the TC repeater.
