I find the Asus P6T Deluxe V1/V2 to best the best board out of the first generation x58 offerings. It has drawbacks but it's a really really solid motherboard and it's totally impossible to kill. If you need PCI and run SLI you can not use a video card that is wider than two slots in the first X16 slot and if the PCI-card is very long it might hinder the cooling of that video card a bit. If you do not run SLI you can use the second x16 PCI-E slot for the video card and use two full lenght PCI cards without them blocking anything important. The second X16 PCI-E slot can handle a triple slot card (and even wider if there is room in the case).
The slot placement on the P6T-Deluxe is almost perfect. I would have preferred a third PCI-slot instead of a useless crippled third PCI-E X16 slot at the bottom of the board but that is my only complaint. A motherboard that can run SLI with a dual slot + a triple slot video card and use a PCI-card at the same time is awesome in my book. There is also a PCI-E x4 slot above the first X16 slot that could be used for fast storage.
Here in Sweden these boards are easy to find for 25-75 euro, often including CPU and memory.
The Rampage II is also good but rarely cheap. The Rampage has a large Fujitsu Capacitor that will fail sooner or later but it shouldn't kill the board . The second X16 slot blocks the PCI slot so no SLI + PCI.
Among the second and third generation X58 boards I have less experience, especially with cheaper alternatives. The newest X58 motherboard I own is the Gigabyte G1.Assassin. The G1 Assassin is a cool motherboard and overclocks well even tough it has an odd VRM design but it isn't a cheap and it doesn't have a PCI-slot...
In general, in my experience, Gigabytes X58 boards overclock memory better but can not cold boot really tight timings which is annoying. On Asus it's more if it works it works.
