If you could afford them the 305 Barrels are one of the best value lights there is.
I have a pair of Swarm Wash FX and they are a very good light, with lots of features.
The Derby effect is decent, just like the the swarm 5.
The Strobe is very good, i like that feature a lot.
The Laser i dislike and turn it off, but only because i think red and green lasers are cheap it does fill a room very well though and if i did Kids parties i'd leave this on.
The Wash is very Good, it could have been one of the best lights available if the LED's could be colour mixed individually. In DMX you can only set it to be RGB or UV, not a mixture. If it could have been colour mixed you could do some truly amazing things with the wash via DMX and it could look much nicer from the front.
For example if you want to wash the B & G in Pink, 4 of the LED's will need to be on Blue and the rest on Red.
Probably worth its price tag if you are going to use them all the time as they do a lot.
