More Lens or better Glass?

The Title gave it away a little but I feel like I should post this as its been running around what I laughingly call my brain for 2 days now.

I have been looking around for good deals on the Canon 7D. I found out that from digitalrev.com I could get a the body with an 16GB CF card, EF-S 18-135mm (f/3.5-5.6 IS) as well as a EF 50mm (f/1.8 MK II) for (only) £1,417.68.{LINK}

So thats 2 lens and a memory card for only around £100.00 more then the body alone...

BUT!

Then I saw this deal {LINK} The body with a battery grip, Extra battery and Canons EF 24-105mm f/4.0 L IS USM for £1,951.93

I know to some you would think the 2nd deal is not as good, less glass for more money. But that lens is an "L" lens (Canons best lens) with weather selling, better build and a fixed aperture of f4 all the way from 28-105mm. It is a hard lens for a tough camera and they will suit each other very well.

I know this is alot of money and to not think of this now would just be stupid, but as i'm losing all my lens to swap to a new brand having the other 2 would be easyer and cheaper but getting this L glass would be much better in the long run!

What to do, what to do......
