I heard a lot of positive reviews for Custom Bellows in the UK, but the 6-8 week wait is not going to cut for an upcoming trip. Does anyone have any experience with the (cheaper) bellows found on eBay? They seem okay from the ad photos. I know, you get what you pay for. But, if it's light-tight for a year or two, I'm perfectly fine with that. I need a new bellows for a Technikardan 45s. Any thoughts? Are there other alternatives?
