The one thing I've learned in diving is that it isn't a good deal or price if it doesn't do what you want it to.
If you haven't already done so, suggest you take some time to decide what it is you want out of your dry suit (cold water or warm water or both, dry gloves, pockets, front vs rear entry, latex vs neoprene seals, type -and corresponding bulk - of insulation you plan on using, where you're going to be walking and what type of boot or shoe you need, etc.) and then look for the best deal on the suit that fits the bill. If it costs $1,000 but doesn't work or doesn't fit you, then you just threw away $1,000. If it cost $3,000 and helps you dive well, then you made a good investment. (That's not to be confused with the more you spend the better things are - a great diving myth of course).
If you're serious about diving, then spend what it takes to get what you need. You will be living in it for the next 10 years or so if you take care of it and keep on diving. Plus a quality suit does have a reasonably good resale market, should your diving plans change down the road.
