Just when I was looking for a NEW dive buddy! (Sorry Dave, he has a BOAT...I guess you're OUT)
No really, Tom in Frankenmuth here, welcome to the board and to the wrecking crew. We have been discussing getting a boat for the last year or so, but have not managed to do so just yet. Diving Higgins Lake would be a LOT easier from a boat as you wouldn't have to make the 'Death March' across the sand flats that 300 yards or so to get to waist deep water where you could swim. We'll keep you in mind for the next time we want to dive at Higgins!
As for the gear, there is lots available here on the scubaboard for reasonable prices, and if you are certified, rentals at the local dive shops are a lot cheaper than buying your own. I can fix you up with a couple of pieces depending on what kind of diving we are doing. Dave and I have plenty of extra kit between us, if we are not diving with the ponies rigs in deep water.
Again, welcome to the Crew. I look forward to meeting and diving with you!
