Please do. You are a professional as outlined in your first post. As such, I'm sure you understand the value that going with a piece of equipment slightly more than you anticipated in the long run ends up money well spent. Lasers, at this level, are not an inexpensive endeavor. It's a harsh reality and many of us have made mistakes and squandered many thousands of dollars thinking, "if only I had gotten...".
I've got lasers four times the cost of that Pluto that sit in a closet and haven't been fired up or used for a show in 6 months. I'm not making any money on them sitting in a closet. One of the biggest things we do on this forum is try to help steer people in the right direction and hope they don't make some of the bonehead mistakes we may have made. You've already taken a big step in getting a quality software program in Quickshow and often it's the other way around where people try to chintz on cheap software - iShow for example and you bang your head on the wall knowing people are wasting their money and simply don't listen.
I don't work for Lightspace or make any money by suggesting it. I just know from having about 20-22 RGB laser projectors that the performance/dollar (or pound in your case), that the Pluto II is pretty damn hard to beat. As mentioned, I don't know the currency conversion in your case but, the price in American dollars converted to pound sterling would make a Pluto II RGB2500 cost about 1,085-1,341 pounds which sounds like it should be in range of what you first mentioned. It might make sense, if you can wait just a little bit, to get in on what we call a "group buy" that should be taking place in a few more months and enable you to get it at a discount versus what you may be asked to pay as a "one off". Things are always cheaper in quantity and Lightspace will ship them directly to the purchaser.
It's funny that as I'm reading threads about bashing some of the "spammers" or companies that come on here to sell things without adding and value to the forum, that I almost have sounded like one in some threads where I've shared my experience with Lightspace and their projectors.
I don't think I linked to you a review of what we are discussing:
Here is one and it's a rare thing that 4 pages of comments have been devoted to a single projector.
