Up today from Forgeworld is a an excellent set of pintle mounted weapons for your tanks. While I generally have enough storm bolters, items like heavy flamers and melta weapons are sometimes harder to make sure I have enough of. Not to mention that a little work, and you can have extras of these weapons for other models. Great release in my book. Also up are the Space Marine Rapier Quad Mortars for both standard games of 40k and the Horus Heresy, with rules.
Here is where you want to go for more pics and ordering.
