Has anyone ever attempted an engine rebuild on their 240d. If so, how hard was it? Does anyone sell a good kit?

A mercedes diesel engine is rebuildable by pretty much anybody just as long as you keep in mind that it is a fairly complex engine. Nothing to really worry about just remember that its not your standard sbc.

Take it to a good shop if you don't know what you're getting into, you'll save a lot of time and anxiety.
Check the online parts sites, some will have various internal engine parts.

The thought of attempting the equivalent of open heart surgery on my beloved 300D scares me to death! I'll leave it in the hands of a professional.
Yes Honey! Thats how they sound! Its a diesel!

I've rebuilt a 300 engine. If you've got the time, the tools (nothing too exotic), and the inclination, do it. Why the heck not? You'll save a lot over having someone else do it for you. It's an engine made of high-quality parts, certainly, but I wouldn't say it's particularly complex.
On the other hand, if you need to finish in a week or less, don't have any workspace, and the task of, say, adjusting the valves makes you nervous...maybe it's best to let someone do it for you this time.

There is no "Rebuild Kits" like you can get for a Chevy; with a reground Crank and Camshafts + bearings and stuff.
The only issue I have read concerning Mercedes being differnt from other Engines is that the is a balanceing proceedrue. You would have to read the Factor Sevice Manual to get info on that. If you can reuse the Pistons and Crank Shaft as is that avoids any balancing issue.
I really would depend on the condition of your Engine.
When I was in Tradeschool what they did is if the Pistons themselves were still within specs they reused the Pistons by Boring and Sleeving the Block (this was on 180Ds). Sleeves are around $30 each while a new oversized Piston is close to $250 or more each.
The biggest stumbling block is the cost of the Parts; mainly the Pistions; if you buy European made ones. Rebuilding the Engine can easily exceed the cost of the Car when you bought it.
If there has been no Bearing Failure and the Oil/Filter Changes have been done on the Engine you might find that the Cranshaft is still within specs and can be reused as is.
The next big expense after that is if some Valves need replacing.
I have no Idea anymore what the labor cost to have even a Gasser Cylinder head overhauled. But, few people have the equipment to do that at home so that and having the Block Bored and Liners installed would be the major Labor expense.

They have a Mercedes Diesel Engine Rebuilding DVD at that benzproducts.com site, it is over 4 hours long. For the 300D and 300SD -Good to watch it done a few times before trying to do a rebuild.
