Definitely not overhead - I'm too claustrophobic to do caves or wreck penetrations - as much as I would absolutely love to, I know my limits. The 330ft dives I want to do are down to some wrecks and the coelacanths at Sodwana Bay. That's all a long way and a lot of training away though.
Keep in mind, and you'll learn this in your training, at 330ft dive will be an overhead environment dive... even if the physical overhead is not there. A 330ft dive will rack up a pretty signficiant deco obligation. So since your claustrophia wont kick in... that should make you respect deep dives that much more.
If you are worried about the cost of a backplate for eventually getting to 100m dives, I don't think you understand what it costs to do 100m dives.
Two computers, three additional regs/gauges (two of them needing to stay O2 clean), new wing, lift bags, reels, lights, the list goes on...
Then the training side of it. AN/DP, Trimix, Advanced Trimix are the courses you'd need to knock out a 330ft dive. Those courses alone should set you aside $4000... and that's not counting the helium charges.
Don't let that discourage you. Just know its a journey.... at 330ft, dives require a lot of training, dives, and equipment along the way to get you there... enjoy the ride.
