Ask yourself what attracted you to this set up.
If you like the look of the kit, have confidence in the brands, and it is all within budget then that really is half the battle!
After that the only advice I offer is to firstly find unbiased online reviews (There are hundreds out there, dive mags often publicise test results online). Try the kit on if you can. Then if you're still happy, find a good price!
In my experience, you will always have small annoyances with anything you buy (whether it be for diving or not), but it is a lot easier to overcome these annoyances when you have gone with your gut, done the homework and found the discount.
If you're gonna be doing a lot of traveling (flying), compare weights with other kit. This has always been a top consideration for me as excess baggage charges are getting more and more ridiculous all the time, and airlines are canceling their allowances for SCUBA gear one after another.
Best of luck!
