Yes, if i had the choice to do it my way, LTCC/Delteq would be my choice. Unfortunately I just spent 1500 on a transmission rebuild for the beater, so funds are a bit tight. Having two cars is nice, except when they both fall apart at the same time.

I've had a ebay opti for about a year, it works great never misses a beat.

I put a new delpi unit from thepartsladi on my 94 and about 2 weeks later it went out from getting oil on it. I didn't have another $300 at the time to buy an OEM unit so I got one on ebay for about $100.
When I put the ebay opti in I also replaced the opti seals, which is probably why the other one went bad.

I drive it everyday and it has run great ever since.
It's a non vented opti.

I also have a 93 Z28 about 2 years ago the opti went out and I ordered a reman opti from summit for $249. I put it on the car and it would not fire, so I took it down to the shop and it turns out the drive mechanism was off 180 degrees, a defect of the manufacturer.
$600 later I installed a new GM opti and it has worked great since.

Summit refunded me for the opti, but I was not reimbursed for any labor.

Default oem - cardone

Well the oem style lasted a few months and a few thousand miles .......
Before that a chandler opti would not even start....

Maybe it is time for a cardone unit from auto parts store down the street, at least I will not have to pay return shipment .........

BTW, OP, thanks for your post!
