Also, the boxes kick out more smoke and use more fuel than the remaps usually, unless you have a very lean map in the box and then you won't be getting what you wanted. You can get very cheap tuning boxes to take in and out which for most people would be fine and often gives more power than the remap. If you strech to the remap boxes, you can stick them in and out still and you will get a much more civilized increase with better economy.
I've abused, sorry used both extensivly and even together and I think it falls to the simple questions below...
1) how long do you want to keep it
2) how many miles do you do
3) how much are you willing to pay
4) Do you have a DPF
If you want to keep it a long time or do alot of miles and are willing to pay or have a DPF then get a remap box. If you aren't going to keep it more than a year or two, don't do many miles, don't have a DPF then the tuning box is a good alternative and can be had for under £100.
