But I rarely buy electronics and don't have cable TV.

I'd replace the breaker, I don't suggest you try as it seems you aren't comfortable with electrons running through wires.

You can simply ACH (electronic transfer) money from your HELOC to a checking account so you could make the payments with the HELOC if you had too.

I am just a customer.Disclaimer 2: Not commenting on what the OP is actually doing, simply for how to sign a document online.To have someone electronically sign documents you can use Authentisign by Instanet solutions (Google them).

First of all, major retailors charge thousands for furniture and electronics they have manufactured over seas for pennies and I did emphasize on the "over priced" crappy 10k necklace zales sold me for over 1.5k that probably amounted to 40$ in gold weight. 

The TV companies will install equipment without the landlord's permission, and they absolutely refuse to take their electronic litter back. 

I just used values from zillow "sold" values and sent I think 3 comparable examples electronically.  

Everything else was remote and they were all using electronic programable door locks.  

Although I'm a techie, I went through engineering school using the slide rule because electronic calculators hadn't been invented yet.

We did the application and all docs via electronic means.What I ended up with was a HELOC that had 1.99% interest for the first year and then prime + their internal rate (based on my credit score) for any remaining draws.
