If you fund a mining hardware for bitcoin, is that expensive? How much will it worth?

It totally depends on its processing power. The more Hashes it can perform per second, the more income it will generate you. Keep in mind that the more hashing power comes online, the smaller your piece of the cake gets. There are 3600 Bitcoins distributed every day (on average, it fluctuates due to variance), they're effectively distributed between everyone, who is mining, depending on their respective hashing power. The more hashing power gets online, the less your piece gets in comparison. - This is a very simplistic explanation but it should give you a rough idea!
It also depends on how much power the miner consumes... The more it consumes, the higher your electricity bill will get!

Can you actually mention the hardware that can be used for that?

You can use any sha256 ASIC to mine bitcoin.
Example 1, Antminer S3: https://bitmaintech.com/productDetail.htm?pid=000201409100729132701XzQIXcc06AB
Example 2, SP20: http://www.spondoolies-tech.com/products/sp20-jackson-october-batch-1
Example 3, ASICMiner Tube: https://bitcointalk.org/index.php?topic=735728.0

Or maybe a cheap block erupter only for learning purposes because you will earn more coins with faucets...
