If you don't mind using tape, would recommend the new Sony (VX1 I think - I can never remember numbers) that is coming out this month. It is entry-level professional quality, will be the same size as the PD150/170 (so smaller than the first gen entry-level HD). Has proper XLR(?) mic inputs.
Otherwise Panasonic have several hard-disk recording cameras. However I'm not sure if there is anything pro-end available and affordable that is tape free.
But as mentioned a wide angle lens adaptor is CRITICAL. I can't stress this enough. And if you can't get good natural light, get a toplight (one of the new LED ones that takes the same type of battery as the Sony cameras would be good).
And if you want compression tips, you know where to come
