Only have the table top Rondo which I swear by. Mind you I am Swiss, so I am "skewed" to buying Swiss quality. Still, I will never let that thing go.
The best thing to do is trot down to a bakery supply store and check out the machines themselves. Do not buy on-line!!!!! On-line sellers won't give you service or replacement parts.
Here's what to look for:
-1 yr warranty on parts and labour. If the mnfctr can't/won't give you at least a year, walk away.
-UL (underwriters lab) sticker. If any machine without this sticker/badge overheats or causes a fire, your insurance company will walk away and laugh in your face.
-Stable tables. No thin guage crapola, the tables have got to be rock solid.
-Scraper assembly. Should be easy to remove and clean. Replacable parts should be available from the bakery eqpt. store
-Belts. Replacement belts should be available.
-Easy forwards/reverse switches. If the switches are "weird" or uncomfortable, walk away.
-Thickness guage should be easy to operate and lock firmly in place.
-Rollers should be heavy s/s or heavy nickel plated. Never, ever, ever never let someone talk you into nylon rollers, this is for pizza and not laminated doughs.
I swear by Rondo, although there are some decent Italian brands, Fritsch is German, Americans seem to have really weird and awkward machines, Asian stuff is all over the map.
