No direct experience of the Technics P50 - it's very piano focused though... Some decent reviews on Harmony Central, some by folks who appear to know what they're talking about.. Appears to need EQ'ing for live work..
Equivalents would be the Yamaha P range (P90/P155), or the Roland RD300... There is a Yamaha CP33 on the bay at the moment for £450 which is slightly expensive, worth a £350-£400 offer direct if no-one bids on it..
Again important to know what sort of music you're playing...
Cheers
