I wish I had run across this thread before ordering from Lido Mounts. It seems that I am experiencing a repeat of what so many others have complained about with this company in the past. It does not appear as if much has changed, despite Jim saying he was turning over a new leaf.
I ordered a mount for my FTM-350 on 2/13/12. After hearing nothing for a week, and living just 30 miles from Irvine, I placed a call and got a reply that it was back ordered and would be going out on the following Friday. (24th).
I got an email from Stamps.com on Saturday, the 25th, and since then nothing. No updates from the tracking number, the post office has no record of receiving the package, and now I cannot get in touch with anyone at the company.
All phone numbers, including the one "Jim" gave me, which he said was his cell number, go directly to voicemail and no calls have been returned.

Monday I am going to cancel my order and get the parts elsewhere. I have located what I need at

I would suggest to all to think twice before placing an order with Lido Mounts.
Just my experience, but not a very pleasant experience,
