equipment booking system

Well, going over my previous post about booking systems it looks like my requirements are a little too niche. It appears there is no 'out of the box' solution. I shall review my needs below:

• booking multiple equipment at a time
• book day and time for pick up and drop off
• view availability
• 4 time slots per day
• all through online interface
• active directory logins

it appears jomrez is almost there, but lacks time slots and multiple items.

The only one which hints at all this is R&R, which is more of a custom build. No pricing up front, but they do demos. I shall chase this one up.
