Hi Laffslast, welcome to Scubaboard. I just bought a brand new set up myself, and although I'm not a master diver, I am a master "shopper". One thing I can suggest to see what kind of deal you're getting is to call the guys at scuba.com (800-34-scuba)
When I was struggling over my purchase I chose them for the following reasons:
1. They are authorized to sell that they sell, so you don't get an aftermarket warranty
2. Although their advertised price might ot be as low as say "Leisure Pro", they will match any advertised price, from either authorized or NON- authorized sellers, so long as they can verify the reseller has the item in stock. That was huge. Translation: I bought an Oceanic regulator, computer, and BCD at Leisure Pro's price with a real Oceanic warranty.
3. When you call them you will be speaking to an actual scuba instructor, not a phone order taker.
4. Shipping is beyond reasonable. I had two sets of Apollo fins, two BCD,s two regs, two octos, and two computers shiped from CA tp NY for $18.
Back to your original question, why not call them and just get a quote to see what kind of price you're getting on the equipment you're considering. You may find you can get it new for the same price.
Anyway, there are also lots of good reasons to buy from your LDS if you don't mind paying a premium. It seems they are giving you a lot of service and support for what they are selling. There's a lot of value in that, especially for a new diver. I didn't have a strong relationship with an LDS here as I'm not from this area and I don't dive locally. Financially, this was a bonus because I got my entire set up for what my LDS quoted me on just the reg, octo, and computer.
The last thing is, being a fairly new diver (less than 100 dives), I wasn't comfortable buying anything used or refurbished. Maybe down the road when I can really take the stuff apart and "McGuyver" it when I need to, I might consider something gently used.
You seem to have that covered as I'm sure your LDS will do any McGuyvering for you as well as maintaining it. However, keep i mind your gear will not always malfunction at home. If you travel as I do, it's nice to have a manufacturers warranty for parts when you're far away from your LDS.
Anyway, good luck with your purchase, and have many happy, safe, and fun dives!
