....try a GOOGLE search for each model...you can likely compare 'specs' that way...Plan 'B' is if you bought it locally take it back to the store and compare yours to the 2008 model in person. My dive buddy has been using a older ( 3 years maybe ?) version....which I'm upgrading her out of this weekend, as I'm almost done assembling her new BP/wing (DR Transpac/Oxycheq Mach V 'Extreme' wing/ DR AL back-plate/Oxycheq STA/Halcyon intergrated weight system) this morning.
The Islander is what is it is...a cheapie/lightly built/travel BC...and her 'older' version has a S*CKY velcro weight system.....sure, worked fine when new, but velcro wears out quickly and eventually became completely unreliable/dangerous...NO MORE VELCRO I vowed !!!
...make sure your model doesn't have a velcro-only weight system....eventually you'll grow to HATE that !!!
The Islander, like all pre-built BC's, is a pain in the butt to modify/add accessories/mounting points...but that was something I learned the hard way after buying my first BC...a Zeagle Ranger (which I still own and keep in reserve or for weight restricted travel trips.)
...my buddy likes her Islander though......other than the poor weight system...and the inability to add/modify it to stow additional gear.
