I have the same size issues as you do. I've done a lot of searching for sources.
The only off-the-rack sizes close I found were at Harvey's
http://www.harveys-divesuits.com/.
Henderson "Hyperstrectch", as mentioned above, is good from all the reading on this board and they will alter to fit if you need to. Just outside my budget.
The other alternative is to go "custom" but, it really isn't as bad as you might think on cost.
I did buy a custom 7mm FJ/J from Aqua Flite at considerably less than Henderson and have been happy with their service and quality so far
http://aquaflite.com/.
I just recently got a quote on a 3mm from Liquidfit. If the product is anything like the service in responding to my request for a quote, then they are pretty good on the custom side. There are certainly quite a number of positive threads on them
http://www.liquidfit.com/.
There were a couple of good reviews on this board about Atlan
http://www.atlaninc.com/.
As for Triple-L, you can't help being curious and cautious about the price but, there is plenty of comments on them in this board.
I'm not going to push anyone's product here. Just offering some sources to look at. As for FJ/J vs Jumpsuit w/hood, its a personal choice.
Good luck on your search.
