I have friend who hates his USIA Techniflex, one who loved his (but when he replaced he didn't get it again) and one who hated hers so much, she returned it for limited store credit after 2 dives. Major issue she had was fit, which is part of the problem ordering online (ordered from DRIS).
I personally have an OMS San Diego ($1800). Now produced by DUI. Only comes in stock sizes, can't get it custom. I love the trilam suits, hate putting on my wetsuit, so putting on neoprene drysuit isn't much better. Comes with replaceable zipseals on the wrists and neck, so easy to swap out if you rip at the site and at least don't have to send it out and be out of commission waiting for the seals to be replaced. I use SI tech drygloves, but can also get the zipseal drygloves that attach direct to the zipseals. I already owned the SI tech gloves, but also like that the seal is still there underneath the dryglove incase my glove gets a hole or connection leaks. It comes standard with 2 pockets, big with bungie cord attachments inside. Comes with hood and drysuit hose if you buy new. I also like the attached boots personally. One less item to forget, quicker to get ready. Have also had some friends that have had fin issues with rock boots over drysuit socks... that the foot kind of slides around in the boot when you kick because the fin strap pressure is on the boot rather than on your foot. I always rinse my gear after diving anyway, so sand on them is only temporary until I get home and rinse everything off... so no issue there either. The traction is also quite good if you do entries over rocks... but maybe just a sock with a wetsuit shoe may work for your sandy pond entry (no concern of fin issues then or about sand on the suit).
Definitely like the suit, dive Massachusetts almost every weekend all year long. Use the wetsuit in the summer and drysuit in winter and early spring.
