I've been ordering from TIPS since the spring, but mostly order them "super-sized" to suit 60mm XForce figures. I do have a few 28 mm versions and have no complaints. About either size, actually.
The only thing is that, to keep the prices down, YOU have to do the clean-up of supports, etc. So there is more work than if you bought on ebay or etsy. Of course, when you are buying those sites that time and labour cost is built into the price!
