Best brand coax and F connector for HD cable?

["Rogue Petunia" <FakeAddress@xxxxxxxxxx>]

hi,

Ever since I got a HD cable box and a plasma TV I have been having
occasional signal loss (total loss of picture and audio, as well as failed
DVR recordings due to signal loss).  I've exchanged the box and still have
the problems, so I don't think it's the box.  Next, I will re-do the
interior wiring to get rid of the 2 splits that exist and doing a straight
homerun from exterior of building to cable box.

The thing is, I don't own the installation tools for cutting a custom length
of quality cable and attaching connectors.  I don't want to buy Radio Shack
RG6 and a hex crimper. That's how the interior wiring was fashioned to begin
with 2 years ago, and if the wiring is the problem I want to fix it not just
replicate it.

My local cable company, Time Warner, uses Beldon DuoBond III coax with PPC
EX6 XL connectors.

If I buy PPC EX6 XL and Belden coax, I must also buy the installation tools
(expensive for one time use).  On the other hand, there is this guy who
makes up custom lengths of RG6 Quad Shield with Thomas & Betts Snap n Seal F
connectors.  Way less expensive for me than buying installation tools!

So, to make a long question short, which would be better:
1.  Belden Duobond III with PPC EX6 XL connectors (must buy my own tools,
over $70, plus $35 for cable)
2.  SCP quad shield with Thomas & Betts Snap n Seal connectors (can buy from
guy already made to length for $30)
3.  Perfect Vision quad shield with Thomas & Betts Snap n Seal connectors
(can buy from guy already made to length for $30)

I spent $2000 on the TV, so I'm not trying to cheap out here on the wiring;
just trying to make the right decision.

Thanks.
