Star Star..... from experience selling....price will vary by fit and features. There are basically two types of construction....FLAT LOCK Stitch and GBS-Glued and Blind Stitched. Heres an overview of them.
FLAT LOCK: PROS: Strong, flat, and interlocking for strength.........CONS: Allows more water in right away...allows water to circulate a bit more = less warmth.
GBS: PROS: seams are sealed and do not allow water in = MUCH MORE Warmth. Jump in and almost no water comes in. CONS: Costs more.
Most price point suits are Flat lock.....and material they are made out of has less stretch. Less stretch means more work....typically not as good of a fit.
That said, the more "cuts" in a suit...the more the suits will cost....as well as materials used...and then the type of stitching.
It all boils down to your wallet and level of comfort you want.
We primarily carry Oneill in the shop...mainly because of the quality and fit of the suits. Over the past 20 years...we've tried virtually every line...and hands down we have had the best luck fitting Oneill. That said, there are lots of good brands....but try them on. Every brand fits differently.
As for pricing....In Spring Suits...I can give you Oneills lineup we carry:
http://www.perfski.com/wetsuits/spring-suits
Reactor Spring: Flatlock 70% stretch material. Good basic fit. Price Point: $69.95
Hammer Spring: 100% stretch material, better neck fit, Flat lock.
Hammer Long Sleeve Spring: Same as above with Long Sleeves.
Gooru GBS Short Sleeve Spring: All Gooru Superstretch Rubber, more cuts = better fit. GBS construction = more warmth...but more $$ c/o from $89 to $159
Gooru GBS LS Spring: Long Sleeve version of above. The warmest most comfortable spring suit around....we sell LOTS of these despite the price. Alot of
people don't want to go to a fullsuit...and use this as an alternative. Expensive...but for alot worth it.
Just some ideas...good luck with your search....and again, if you are buying closeout / off price suits that you don't know the brand...TRY THEM ON!!!
On the major players like Oneill....use their size chart with confidence...its time tested. Keys for spring suit is height, weight, and chest measurement.
Good luck.
