I don't like my single piston disc brake. it's almost like black magic in trying to get one of the disc brakes to not rub, because the rotor is never totally true, and one of the pads is unable to move. adjusting it is also a pita. I imagine this to be a non issue with dual piston disc brakes. any suggestions? I'm trying to go as cheap as possible.

Hydraulic or Mechanical?

Guessing you have mechanical as a single sided piston, as in only one piston normally on the LHS of the caliper only, with the RHS being fixed.

If Mechanical there's not a lot of options, there is this Rever MXC1, Unboxed & Weighed: Rever MCX1 dual piston mechanical disc brakes ? plus first ride impressions which looks to be very similar to the TRP Spyre road brake; that's about it.

Shimano Deore hydraulic --- big league braking at a small price

IMHO - Avid stuff is not worth the price of the box they come in at the budget level

I think I'm limited to mechanical setups.. my goal is to have something like this

Not quite sure what type of bike that is, but it's not an MTB!

If that's yours? does it even have disc mounts? as that has caliper mounts (and brakes fitted) and it's unusual to have both fitting for caliper and disc brakes on the same fork (and not just a hole where the reflector can be put)

not mine. mine has disc mounts

not building a mtb.

The pictured bike has TT levers in addition to Shimano bar end shifters. TT levers should work with mechanical brakes like TRP Spyre and Avid BB7. I have the Spyre's on a similar bike (traditional short-pull brakes and separate shifters) and they offer more of a "caliper brake-like" setup and adjustment compared to the similar brakes which don't have the "hoop" design. They've got awesome stopping power and decent modulation. The factory pads can be a bit fussy, requiring a sanding before settling in. The same pads are not recommended for wet weather use but I've yet to hear any complaints from my son, it's his bike.

Mechanical disc brakes are really the only option if you're using "reverse-cable" levers such as those TT levers. Almost all hydraulic systems, made for bikes, route the hose out the front of the lever and that would be a challenge to manage on a bike with bull horn handlebars unless you mounted the levers on the flats or reversed. If that's a consideration, I recommend looking at mid-grade hydraulic calipers rather than the mechanical caliper design. I don't think you'll need "top of the line" brake power but why not get a strong set if you can fit them on? Something like the Shimano Deore's mentioned above would be a good choice, IMHO.

My current project bike is going to be similar to yours. I will used a CX type frame with hydraulic disc brakes, 700C wheels, and flat bars. I found a pair of Avid Elixir 3's on sale and will be giving those a spin. Not sure about shifter's though. Possibly the 9-speed Deore triggers which I already have.

Sorry for getting off track. Good luck with your build.

No more off-track than the OP posting that skinny-tired abomination in the MTB forum.

Not sure about budget...but they are pimp.
