Personally I dislike Corner desks. I also hate my back to the door. So.......yeah. As for overpriced, the Ikea Gallant is very reasonable for just a base desk, around 110. It's only when you start adding different legs, extensions, cable management trays, etc. does the price climb. But then again that is what makes the Gallant attractive, you can build it to suit you.
The one problem I have with IKEA desks - based on my experiences with two of them - is that if you ever need to move, they're damn near impossible to take apart; but they're also not quite sturdy enough to move while put together, without stuff breaking or becoming misaligned.
/shrug, Mine has survived three moves. I have fully dismantled it and put it back together three times now. Its still as rock solid as the day I bought it.
