I'd say it wasn't worth it. Your photos won't look much different. Invest the money in lenses, tripods and filters instead if you do a lot of landscape photography.
Hi Jo,
Thanks for the help/response.
Yes i think it will do the job for years to come. Was tempted by the high IQ of the high iso in the 550d.
Need some more thinking i guess 
inc. the am batteries that came with it. i received my grip on the 15th of june, charged the batteries and they are still in the grip havent charged them since
have taken a fair few shots too and still appears to be "full". Also doesnt feel different to the original, pretty much weighs same, same size and feel.
