First, look at this:
That's Forge World's lovely Javelin Attack Speeder. Now, look at this and explain to me if there any point whatsoever to taking a Land Speeder Typhoon. Seriously, only the Dark Angels can match it for pts cost, and even then the Javelin has the armour of a Rhino, AND it's Cyclone missile launcher is twin-linked.
1. It's 15 pts cheaper than a Land Speeder Typhoon (except for cheapass Dark Angels).
2. It has more armour.
3. Its main weapon is twin-linked.
This is quite possibly the best use of 75 pts possible for a Space Marine player, and guess what? It's available at Forge World for the paltry sum of GBP55. Yes, that's right, 50 pence shy of THREE TIMES the price of a Land Speeder. You know what, Forge Word can go f**k themselves...
