Novatech good
Ummm.... some melons in there as well.
Scan: their ordering system makes no effort to reserve stock at any time and seems to be inaccurate in any case. Dropped them after the 3rd consecutive order got stuck in a deadlock, with different parts taking turns being out of stock holding the entire order up. In one case they discontinued a part, permanently stalling the delivery but never noticed, even after 2 sessions with customer support! Can't say I've ever been impressed by their customer service.
Aria: RMA'd a mboard to them and eventually received back a considerably lower spec version, covered in shit with a randomly chosen set of accessories, some rusty. Took weeks to get that far. 3 years on I'm still waiting for a real replacement or refund. Or even acknowledgement of the return.
...I trust ebay more than some of the others... ;)
Novatech became my automatic choice for most things, after the sad loss of Komplett. They just seem to get the job done without all the gimmicks, haven't let me down yet.
