I've found them extremely unhelpful on the three or four times I've called them. They seemed to never have anyone who knew about their stock, despite the items being shown in adverts & on their website.

The attitude was so of putting I decided that's it I won't contact them again.

Rollieflex's are easy to find and at better prices for a good camera, manuals or guides are easy to find on the Net, unless you want something very up to date go for a 2.8/3.5 lens in an E or F, probably half the price you looked at, try FFordes, or someone else reputable.
