According to the manual, you can use a standard PSA adapter with the BE-5. I think �35 is a very good price. I don't know the BE-5, but I can't imagine it not being worth the money.
I know a few people who has this(one still has and uses it regularly) ..it is made of plastic so i don't know how it would stand up to constant gigging but you can get some good sounds out of it and it's very easy to use...i wouldn't be suprised if the chorus was a CE-2 based circuit.....even through my mates crappy amp a knock off LP this unit sounds good....well worth 35 euro...
