What exactly are you looking for?
I've had good experiences with dealmed.com for consumables and my bp cuff set.
One of my companies uses medicsoncall.com for supplies, my airway bag and splint bag were purchased from there. I got my trauma bag from galls. It's one of the dyna-med bags, I'm very happy with it and would order from there again.
All said and done I have over a grand invested in my gear, so that crap gets expensive. I'd avoid paying out of pocket if you can.
That said, the site you mentioned looks to have some decent bags at fair prices.
