Short Version:
Good 25' VGA to VGA (Computer to Projector)?
Good Xbox 360 Premium to Projector (Component or VGA)?

Long Version
I would imagine this has been posted somewhere before, but I've tried to find it with unsuccessful results. These forums are behemoth!

I'm building my first home theatre. For the time being, I'm going to start with a Panasonic AX100U. I would like to connect my Xbox 360 and Computer to the projector. I'm doing a ceiling mount - The nearest I can get a computer is about 25' (Total length of cable needed).

Now the question: Where do you guys buy your cables? Long ago, I bought a belkin VGA. It sucked. The cable made the other monitor blurry as hell. This event has scarred me for life. I am now cable conscious.

I will need a VGA cable to run Computer to Projector about 15' long. I don't really want to spend a lot of money - the minimum possible. However, I do not want to sacrifice quality too much. I do not need the "omg this cable blocks out all bad signals in the world and aliens!!! ZOMG!!!!" - I just want a cable equivalent to a nice Dell 1m VGA to VGA (that came with a 2005FPW).

As for the Xbox - what are you guys doing? Do you guys use extension cables?

So, please excuse this post if its already been done numerous times. I couldn't find it and searches on google don't really yield the results I need... Perhaps I'm just too weary from my past Belkin experiences...
Anyway, thanks in advance.

Edit: Measured it - its more like 25'. Can I run a VGA this far comfortably?

First off - definetly get cables from Monoprice - great cable at unreal
prices, you'll see 99% of the people here will tell you same thing.
As far as 360 - I have my 360 next to my PJ, and am using VGA cable
this way when I put in SD-DVDs it will upconvert to 1080p.

IE something like this:

That does seem really cheap.

I have a 35 foot VGA cable and a 35 foot HDMI cable from Monoprice. I bought their best ones and still saved a fortune.

They both work great!

I'm using a 25 foot VGA cable (I think from Monoprice) to drive my projector at 1280x720. You shouldn't have any problems with it, even at the higher resolution.

Um, I think you need female to male to extend the 360 VGA.

For those of you that have multiple VGA inputs - do you guys have a KVM, and if so, is one from monoprice reliable?
