Hard Time Finding New Motherboard.

Hello I am wanting to upgrade my motherboard (I know how and have done so in the past)

The problem I am having is finding one for my cpu AND has SLI. as most of the motherboards that I find online say "discontinued" I currently live in the UK. and am trying to find one for around 100gbp or higher if need be.

My current setup is.

Motherboard: Intel DH55HC
CPU: Intel i3 550
Heatsink: i3 550 Stock
PSU: OCZ ModXStream Pro 600W
Graphics Cards: 2 EVGA GTX550 Ti 2gb (currently only using one but have two)
Harddisk: Western Digital 1.0TB
RAM: 8GB DDR3


I have no idea why it is so hard to find any LGA1156 Motherboards that are SLI ready.
