I'm carious which methods of payment everyone uses?

Credit card and bank transfer mainly.
We make exceptions only for few old customers
from Israel who prefer to use Uestern Union (I don't know why).

Paypal, credit cards and Interac Money Transfer (Canada only).

2CheckOut, money orders (special occasions) and paypal for a few.

Credit Card, and PayPal

If I were to choose, I'd say PayPal because of name recognition. However, paying with a credit card (and not using PayPal, 2CO, etc...) is by far the most popular and preferred method.

Personally I WONT ever pay for hosting with anything except CC & PayPal. If you are not clued up enough to offer either of those facilities, you probably aren't going to be up to the standard of hosting I expect.

paypal, 2co, worldpay, ikobo, yowcow, authorize.net

in my own opinion, start out with 2checkout and paypal... Once things start rolling, you might want to look into Authorize.NET.

I am starting up soon and I am going with the banks merchant barclays. All my card processing will all be done behind the scenes integrated with the banks systems.

2checkout for CC, Paypal, Money Orders. I want to get a merchant account but am putting it off a little longer.

All my clients pay with Credit Card, and one with Check. We started offering Paypal 6 months ago, but no-one uses it.
