I have a Hagstrom LP24, and I have had no problems with it. I had a floppy drive go bad on me and wipe every disk that I put into it, and wouldn't you know, the first disk it happened to (before I started testing it with blank ones) was the disk with the LP24Config program on it. I e-mailed Hagstrom, and they e-mailed me another copy of the LP24Config program within 20-30 minutes. I just wanted to say that they have excellent customer service, too.
That being said, I also own an Opti-pac, and I couldn't be more please with it. And if the I-pac would have been around when I bought my LP24, I would have gone with the I-pac because of price.
