I've been looking at those pages, and that one you mentioned from Ebay was one of the ones I'd looked at for something midrange.
The only concern I have with the reproduction you mentioned is that I'm not sure if the compartment will hold monarch sheets -- which is the size my man prefers. :) I've been Googling these all day...
Another one I'd looked at was this one:
http://cgi.ebay.com/Mahogany-ladies-writing-slope-lap-desk_W0QQitemZ350105172612QQcmdZViewItem?hash=item350105172612&_trkparms=72%3A1205|39%3A1|66%3A2|65%3A12|240%3A1318&_trksid=p3911.c0.m14
It's missing the key, but otherwise it's beautiful, reasonably priced, and it looks like they'd already replaced the leather on it. It is a touch small though, as the guy said it was probably designed for letter sheets instead of monarch sheets, or would fit letter sheets better. I might just have to get it for myself.... *grin*
Thank you for the help! :)
