I consider $190 expensive for a board (for a consumer). In most builds I design, I'll never usually pick a motherboard over $150. When I was new to this site, I did everything wrong and was recommending $300 Maximus boards out the wazoo, until someone pointed out that it was stupid.
For Z boards, I usually pick one around $140-50, otherwise usually in the $70-90 territory for an H board ATX, or MicroATX I always go with a $50 board. No matter how many power phases high-end motherboards have, or SATA headers, PCIe slots, capacitors in the VRM, it's simply usually better to get a cheaper motherboard since the motherboard has little to do with performance.
I personally would p[ut a $50 mATX board in an ATX case, the money savings are real, but people shun me for that.
