Well Aria are on my hitlist tonight.
just tried to order a motherboard (Finally got roundto it) and a hard drive. They work out £10 cheaper (Even with carriage on) than ebuyer for the same 2 items, added a 1.5 TB Spin Point as well.
7 attempts for them to have my money.
break em, me thinks ebuyer can have the extra tenner if the ordar wont go through 1st thing in the morning. 
Have you tried Novatech
had good service from them in the past although their stock list is a tad limited
Used them quite a lot untill they went bust a few years ago, treated them as dodgy since.
I was fortunate a few years ago.
Bench mark (6 miles)
Computer Trading (4 miles)
Choice (7 miles) (now ebuyer)
Extreme Computers (1 Mile)
Enfine Computers (5 Miles)
All big advertisers in computer mart a few years ago were all on my door step, and with the money I was spending with them got quite some interesting discounts, and knew most of the owners.
That was the good old days when there was a few quid to be eart in building computers.
Plus Scan, Aria, Novatexh, Mesh and many more. going back to the days of the 286 and daiy chained hard drines. When a 1 mb 30 pin simm was £80
