I have a blue point one I got from the snappy truck its digital, and very accurate . Not sure who actually makes it, but it was worth it to buy it from the truck for me because I've warranties the hose once. And I know it'll be taken care of in the future. Almost guaranteed to find the same one cheaper as someone here may know who makes it.
I really would like something with a accurate gauge and the ability to set a pressure and just have it bleed off after it hits that pressure that is preferably under $100
Looking online those appear to be the same as the Astro Pneumatic although I've never actually held the AP in hand, only the Blue Point.
I have to say I'm very impressed with the ryobi unit. Set the pressure and it pumps up to 1-2psi above. It will also inflate the kids toys and comes with all the attachments you need. If i remember right it was $35 for the bare tool.
