If you want an automatic 'point and shoot' type film camera and can't find a reasonably priced Oly Trip, then perhaps have a think about a Canon Sureshot Supreme. It's a black plastic job, so not the most aesthetically pleasing, but it's got an f/2.8 lens and takes well-exposed, sharp-looking photos that you perhaps wouldn't expect from something that looks like that. Price? Expect to pay between £10 and £20 for one in fully working order from eBay. I'll post an example shot from mine later, as Flickr seems to be off-line at the moment!
Basically, if something looks retro (silver and black) then it usually sells for a premium; it's often not performance or feature related. Take the Canon A1 35mm SLR for instance, it's all black and has more features than the AE1 Programme but, currently, the lower spec AE1 Programme tends to sell for a higher price. I can only think this is because it's silver and black and looks obviously 'retro', which to me is just daft. Of the two, give me the A1 every time!
There's no way I'd part with £145 for an Olympus Trip, you could buy an Olympus OM10 SLR with 50mm Zuiko lens and manual adaptor for much less than that; it's also silver and black but will take much better photos. A Canon A1 with 50mm f/1.8 in full working order can be found for around £120, and that will put most other cameras of a similar era in the shade in respect of features and sheer usability. There's a plethora of old 35mm cameras out there, so why pay what can be a significant premium just to look 'trendy'?
