Autometer is definitely quality for a bargain.
Best quality gauges I've ever used (but also paid a lot for): DEFI
ProSport Gauges are similar looking to DEFI but are a much lower quality and they do have their issues. But they are a fraction of the cost. It just depends how picky you are about how they look vs how they function.
Whatever you do, go with remote mounted sensors if your budget permits it. That means, for example, my DEFI boost gauge has a boost sensor with a wire that attaches to the actual gauge. This means I just route a wire to the gauge from the engine bay instead of having to route a vacuum line. same applies to fuel pressure, oil pressure, anything with a fluid running through it is best kept in the engine bay in my opinion. It also makes installs much easier.
When running boost line, I recommend you use copper tubing, which is much stiffer and will not kink like nylon tubing. The cheapest way to get this is to go to a hardware store like Home Depot and get the 1/8" copper refrigerator tubing, it is much much cheaper than buying the tubing at autozone or a auto parts store. Tape electrical tape over it or heatshrink it if you are worried about it hitting a hot wire or anything like that, just so it doesnt offer itself as a ground to surrounding wires.
As for Wideband A/F, I would go with the innovate motorsports kit, like the LC-1, and add on their DB gauge. I liked it a lot more than the AEM kit and it is similarly priced.
