I've seen this kit in a local store for about $6.50. It's a versitile kit, having seen service from Vietnam to Desert Storm. However, is it to scale and is the detail good? (After all, Airfix does not always have the best reputation).

I built one back in the November-December timeframe. It needs a lot of work. Here is a photo, there are additional photos in my gallery. Here is a link to the thread where I discussed the various tweaks I did to the kit: Airfix Sheridan.
