Cost and weight and value for money.

Mmmm, but surely cost is the only part of that sentance that actually applies to Martin kit and if you're scouring the fleebay pages there are a lot of bargain.
I think the key with Martin kit is to discount the older kit - back in the day, there was some huge and heavy martin stuff kicking about, but the newer gear like the EFX range, the mania stuff and so on are no heavier than other kit on the market, but I do think you get a much better product. I've had years of buying Acme, Prolight, Skytec and other cheaper brands and have never been anything other than dissapointed.
Currently running a pair of minimacs - OK a little heavy, but I love them, a pair of T-Rex - superb effect and great optics and a mixture of Datamoons and EVL spins. All bought because of there improved optics.
Don't discount Martin gear yet Robin!
