Notice that they're "their BC's" I've never seen anyone on a trip (and I look at other peoples gear) with a "Tommy D's" brand BC. They're probably just relabeling some generic wholesale brand.
I guess I have a issue with a dive website that has a link to cashlagoon.com on their homepage - a site that pays for links. And sells the same multi-colored 2nd stages as "regulators"
Also I didn't see any mention of a warranty anywhere. But I didn't look at more than the BCD, regs, and home pages.
I applaud the concept of making low cost gear available but unfortunately DiversDirect and others do it so much better in that area...
If you're trying to save money, consider
LeisurePro. They have at least a dozen BC's under $250 from manufacturers you've heard of. And they do offer service and a warranty through them. Understand that it's through them though, not from the manufacturer. It's how they get their prices so low.
Scubatoys also has several BC's under $250 with their SB discount. And they offer a full manufacturers warranty. And service everything they sell.
Call Scubatoys and ask for the the 10% Scubaboard discount, you don't get it ordering online. You even get a $10 gift certificate by posting 10 useful posts on their
forum. And $50 more for 250 useful posts later.
Right now they have an Aeris Atmos XT for $225. And several other BC's in the $279 range - less the 10% that's in the ballpark with Tommy D's. And they're all brand names.
And sometimes the mfr's.
suggested prices listed on their website are just that, a phone call and you can maybe do even better. I have. They're fair, ship fast and will suggest reasonable alternatives if asked.
