Urgent help on choosing amp!

So, I am up for a Markbass head. I currently have two tempting options in used heads, would really appreciate some help in deciding:

- A Markbass little Mark 2 - the old siscontinued model, 500w, used. (the little mark 3 sells here new for 550e)

- A Markbass Little Mark tube 800 - used amp, with a malfunctioning balanced input (which I wont use, and the normal input works perfectly). That is a model still in their product line. new is around 750-800e here.

Both are for sale for 350e

Which should I choose? Or should I forget both?


Heeeeelp!
Thanks!

 

Just to add. I am looking for a used head that can hold up for some years and then sell it again when I have got the money to buy a amp head like a Vanderkley or Trickfish
