if it were me i would just go with a gm opti. i have heard that accell opties have too many problems. and thats the last thing anyone wants is a problem with something that is already a pita. and i have had a friend that had nothing but problems with msd plus they are expensive.but then again some ppl have luck with msd. i guess it is a hit or miss thing. i put a gm opti in mine about 20k ago and iv had no problems.
i went with the gm opti. I ve heard horror stories with some of the rest of them.

+3 on horror stories on Accell's :S From DOA to rubbing rotors to short life span. When all that work is involved in replacing the Opti, it's worth the extra money for a Delco.
What I plan to do, knock on wood, when mine goes out or when I replace the cap is to seal it with a good bead of sealant and drill a small hole somewhere safe and make it vented.

What "went" and did you ever change the cap and rotor? People seem to ignore the fact cap and rotor are wear items, should be part of periodic tuneups, but are usually not done. Then when they act up people blame the design rather than admit neglect.

And locktite the rotor screws before you install it. Most new optis that "blow up" are simply cases of the rotors coming loose and breaking. Don't just take it out of the box and bolt it on. I have yet to see one come out of the box with those screws tight.

I went with an MSD and loctite on the screws. It's been flawless so far and the overall quality of the unit was quite impressive. I do have to say at over 100k my factory opti was still working fine though also. Just went with a new MSD when I threw the 383 in

Can someone clear this up . Are the Delco optis the same as Delphi ? I thought GM sold the Delco parts business to Delphi a while back and Delphi was now the manufacture of GM replacement parts. However a seller on e-bay was selling a delphi 1994-5 unvented opti part number CZ20009 that is made in Mexico for $265.00. It this a knockoff or is it GM equivalent ? Can you still buy a genuine Delco opti ?
