Hey Mate - Excel 2W one-offs are about $12-13K (depending on exchange, cause they sell in GBPs, like £6500, but with I'd dare say the lowest divergence in their class in the market (and therefore, higher brightness) - and VERY high reliability - solid as a brick, and NO bloody cooling fans, all TE, etc - they'll outperform and outlast any Melles I've seen...) it is worth the extra quid for the piece of mind - a good ad for them would be like the ones for 'Maytag' washing machines, from years ago - ya' know, with the ever-bored repair man (cause they just never break!

- for Pro-level work, where you might have a gig with $5-10K or more at-stake, they become your best friend- we ALWAYS brought one for 'back-up' (for Ion-laser gigs, in the days before DPSS WLs) and they have saved our @$$es more times than we can count (when the Client's power or water would crap-out, etc)... at least with the greenies, we could do SOMEthing, and they were so bright, the crowd was just as happy... anyhoo, HIGHLY recommend them, and since they are more on your 'side' than ours, you might even get a better price direct from them... - lemme know if you want to see more pix!...

- peace, jon
