Don't know on the price, other than for 'value' you may as well buy 2nd hand; it's a tube of metal. It's not going to 'go wrong'

Twin dump (bellmouth)/single dump... different methods of connecting to the back of the turbo. One just collects all the gases & sends them down the rest of the exhaust system in a big heap, the other one keeps the seperate flows from the turbine & wastegate seperate for as long as long as possible (frequently this isn't very far). Technically, the twin-dump should be better; in practice they are very similar, except the bellmouth seems less 'fussy', twin-dump can work very well in the right situation. Another guide is bellmouth for lower volume flow, twin-dump for higher (large turbo, really).
But they're just guides
