Another
classic Filmwasters thread.
Poor Emma.....there's nothing like a bunch of wildly differing opinions to help make up your mind, is there?
FWIW, I'd go plastic on the lens, anywhere cheap for the purchase (i.e. not from Lomography), and with or without flash depending purely on whether you think you'd be using it on nights out and the like. I have an old 120SF model (or is it 120FS??) which is the basic model with plastic lens and flash from about 10 years ago. I used the flash a lot to start with because I took the camera to gigs to snap photos of bands. In social situations the flash
did tend to be a bit overpowering though, so tissue paper taped over it was a necessity. I'm not sure the presence of a flash unit hampered the "quality of image" when I wasn't using it though, so unless you're only ever going to take photos outdoors, a model with the flash onboard is probably going to be more useful.
Apparently Holgas come with a bulb setting these days, so you could take still lifes indoors without flash (if you have a tripod or equivalent), but other than that, they are kind of useless indoors unless you use really fast film (and then some).
Also, hark at all the lo-fi monkeys discussing the finer details of a decidedly non-fine-and-that's-the-point-isn't-it camera
With or without flash won't make much of a difference to your photos.
Thinking about it, you already have a Coronet Commander which - one you cut the mask out - is basically a WAY cooler version of the Holga (this is an actual FACT based on FACT and REALITY and the law of obscurity equalling coolness
), so get a Holga with a flash because the Commander doesn't have one.
