Let me introduce the Gigabyte GA-MA770T-UD3P which comes with AMD 770 chipset (770 Northbridge and AMD SB710 Southbridge) and is AM3 Ready.

So get this I spotted this little cute Gigabyte motherboard still with 6x SATA, Gigabyte Ethernet, RAID, 4 DIMM slots, integrated audio, dual-BIOS and the entire Gigabyte enchilada of motherboards features for roughly 79 USD.

Here in Europe you can even pick them up at just over 60 EUR. Pop on a nice value AMD Phenom II processors (as yes it's AM3 ready as well) and you might have purchased a heap, seriously a HEAP of value.
