Hi stevieb and welcome to maggotdrowners.
Got a tardis myself,like the others said its a bit on the heavy side but it does come with a wheel kit so I dont carry mine too often. One word of advice if you are thinking of buying oneis to check what you are getting for your money.When I bought mine I phoned several outlets and got quotes as low as 350 only then to be asked if I wanted the extras ie wheels,footplate,pole rests etc.
It was obvious that these dealers were breaking the package down.You should get the complete system for 450 or less.One other thing to be careful of is the clip/hinges, these are a clever piece of kit enabling you to open up the lids/seat from either front or back.You can also remove or add extra trays as they just clip in,But they are made of plastic and if you are not careful they can easily be broken as I found out when I forgot to clip shut before sitting on the lid and breaking 2 hinges,(lard arse or what)Good news was that a phonecall to Keenets who distribute them was all it took to get me the new hinges and FOC . Hope this info has helped and whatever you decide hope you have many enjoyable days fishing.
