Camcorder models with accessory shoes

I'm currently looking in to purchasing a camcorder to record presentations and interviews. The main requirements we have for the machine are:

- A file format with straight forward play back on a wide range of pcs
- Ease of use
- Accessory shoe so that a flat mic can be used in conjunction with the camcorder

I've made some initial searches and it seems as though there are a couple of panasonic models which might be suitable; namely the HDC-HS300 and TM300. If anyone owns one of these models, or can recommend alternative models, I would be grateful for your advice- we have a budget of up to £1000.
