I couldn't find a decent priced new motherboard for that processor. This is a challenge for consumer motherboards. Most manufacturers stop making them as soon as the volume for the processors they support drops which makes replacements hard to find. It's probably that "hard-to-find" issue that makes some used ones cost more than the mobo was when new. There are a lot of used Z97 motherboards on eBay, including
some for under $80, but you'd be getting an unknown quantity.
I'm with Kleer Kut here. If there's no cheap way to get things up and running for a few years, then don't waste your money because you will never get that money back and you'll be running an old system with unknown reliability.
It may be much better to consider an inexpensive modern system that can maybe be upgraded in the future in a couple years when you're willing or able to spend more money.
For a non-overclocked motherboard, here's pretty much what you look for:
1. An ATX motherboard with the right CPU socket with your specific CPU on the supported list.
2. The right size to fit your case.
3. Brand you trust that has a decent BIOS and uses decent components in their build (Gigabyte, ASUS, ASRock and MSI all fit that bill). A non-branded mobo will have an unknown reputation for component selection.
4. The right ports you need (USB, SATA, etc...)
5. If you using integrated graphics, the mobo needs to have the right video connection for your monitor and support the appropriate screen resolution.
6. The right PCI slots (if any are needed)
7. The right number of DIMM slots for what you're planning on using and support for the speed memory you will be using.
