I've dealt with them for years and referred family who've bought PCs. I had my laptop repaired and they were very friendly, helpful and very reasonable. I've also bought loads of peripherals over the years and always shopped around at the time and found them to be the cheapest. I've used pixmania a few times for camera stuff etc and found them really hard to deal with if anything went wrong with your order - a camera went missing with DHL, took months to get a refund. Anyhow, can't recommend Marx highly enough as you can just pick up the phone and talk to them or call in. My husband's work use them and I think get great discounts for large orders / repeat business etc, they're a university so have a limited budget and find Marx the best for reliablity & cost
