I have now purchased 2 systems from Alpine Systems, EGGD and EGLL. As a software developer for FS9, FSX and P3D I need a very reliable platform. I asked Paul for some extras with the EGLL system including PCIE SSD and 2 Nvidia cards.
Paul duly delivered a very fast machine when he promised he would and within my budget.
I think Alpine do give the finest customer service anyone could ask for (and flight simmers tend to be quite critical!) so I would not hesitate in recomending their services.
