There are many bitcoin services with years of reputation! Hundreds, just pick one!
On a serious note, there was clearcoin (sp?) which is now closed to new transactions, and
http://bitcoin-escrow.i2p/ which only runs on i2p, none of them of course had years of reputation. Read on more services here, but
http://www.bitcoinsreview.com/category/bitcoin-trading-website/, but as usual do your research on particular service before using it.
If you need not an escrow, but a betting site, there (was?) moonco.in but it's not working atm
