Cheers for the ideas guys!
I was thinking of buying a fair few upgrade kits (I have two atm to start me off) but as soon as I saw the shoulder pads and the CC weapons and pistols chained to the wrist I knew it was going to become expensive to have the army look how I wanted with all templar bits on every single marine.
FW has Templar Breathern which look awesome but they have power swords.
The Templar Breatheren set would make fantastic honour guard upgrade with all those swords and awesome looking helmets. It's a shame that half of the box is imperial fists themed though. (I know we are the successor chapter but I like the independent feel
I'll have to check out a few more bits websites and my locals I suppose. The one I regularly used for my Orks is out of all the best bits from the chapter upgrade kit sadly.
