twin/tandem pram help!

mods if this is in the wrong place feel free to move it!

I'm not sure which one i should go with! i've got the two boys (20 months and 3 months) and i need a double pram - as DJ still sleeps in the pram, he's also not yet walking and my front carrier only goes up to 10kg and vic is 7.2kg. plus with us starting play groups ect i'd like to be able to pop vic into a pram.

now my question is - which do i go for? i'm thinking i'll need one that the seat goes up to at least 20kg(each) and the only non-brake-the-bank ones i've fond is the babylove tandom lite and... well thats it! i've checked out the Velco ones and they're a little exxy for me along with mountan buggy (sp?) and P&T dont seem to cater for that weight.

i've thus far checked out ebay - and have placed bids on one baby jogger city minni as well as a Valco Runabout 2 Twin Stroller Pram, the baby jogger is at the upmost end of the budget, $250. along with pramwarehouse dot com. any other twin prams that'll do the kind of job im looking for??
