Behringer have announced a selection of lightweight power amps.

Looks like their version of the Peavey digital power conversion 1U amps to me, but given that I paid £180 for a second hand 350 a side Peavey about 5 years ago, the prices of these amps look highly competitive.

Comparing further with the Peavey's it's a slight pity the higher power amps are 2U but you can't have everything!

This is their loudest 1U 2 channel amp: http://www.behringer.com/EN/Products/EPQ1000.aspx
