How much does it cost to replace the timing belt on a 2004 Honda Element?

I'm looking to buy my first car and I'm looking at a Used Honda Element. The only thing I'm concerned about it that the car has a lot of miles (200,000) and the timing belt hasn't been replaced. Generally, how much would that cost?

2004 Honda Element has a T- Chain and will not require for a replacement unless the chain's links, guides or the tensioner wore out etc.

200K miles is about a little more than an average mileages accumulated for an US vehicle even I've seen an advertise like this for a lot less mileage:

But look at this report from KBB (At Texas):

I haven't heard any problem nor replacing any T- chain on any 04 Element unless there's a problem with the performance of the vehicle. Test drive and then let a repair shop do an evaluation/ check up before buying will help you to determine the purchase price.

Edit: To find out how much to repair the vehicle at where you're at:

Cost will depend on several factors like where you are located, where you have the work done ect. Call some local repair shops and ask them your question, then you will know what the cost will be. Parts prices vary greatly from area to area as well. Keep in mind, a dealership will cost probably twice or more than a local private owned shop. Ask some friends where a good place in your area would be to get the belt changed.
