Miva Merchant: Preferred Payment Gateway/Processors?

Investigating payment processors to use for client's Miva store

[clearpixel]

Hello! This is my first post to the forum (I was actuallt referred here by a client who is very tech savvy). I am now in the process of creating my first e-commerce site using Miva Merchant as the shopping cart. However, I am not sure which one of the supported payment processors listed below I should deal with?

I plan to give my client the information for Miva but am looking for two others to research. It seems there are mixed feelings about Authorize.net, but generally I am open to any suggestions. If possible, I would like to use a provider with whom I can become a reseller. Here are my choices:

Miva Payment
PayQuake
U.S. Merchant Systems
R-P-G (Rodopi Payment Gateway)
E-Commerce Exchange/QuickCommerce 3.0 Payment Gateway
PayPal Instant Payment Notification
Verisign Payflow Pro (PaymentNet)
Verisign Payflow Link
Paradata Payment Service
Credit Card Payment With Simple Validation
Lynk Internet Processing
Cardservice/LinkPoint Payment Gateway
Innovative Gateway Solutions
CyberSource ICSv2 Payment Services
GlobalCommerce Payment Gateway
e-ValuCheck - Accept checks for immediate shipment
Moneris e-SELECT Payment Service
COD
Check Payment
Authorize.Net Payment Services v3.1
debit-it! - Full Service Online Electronic Check Processing

If authorize can get over their DoS problem, they're not a bad company. I used to use Cardservice International, and they're not all bad either, but very bureacratic.

I have a pretty good relationship with my Merchant provider, who currently has me on authorize (yes, I'm having problems, but he's keeping me up to speed on it) and he says he can also put me on Verisign if the authorize problem keeps up.

If you want to sticky-mail me for his info, I'll be glad to give it to you - they are a medium-sized merchant company that seems pretty e-commerce savvy.

Verisign Payflow Pro (PaymentNet) is by far the best one on the list with the least amount of down time and un-notified back end changes.
authorize.net has the worst possible record for not only down time but in changing the back end server configurations with NO notice to client resulting on days of down time with no clue on the merchants part.

We've used all three mentioned (CSI/Linkpoint, Authorize.net, and Verisign PayFlow Pro). The short version:

CSI/Linkpoint: slower than the others, though reliable. Difficult (compared to others) to adjust final totals and to do voids.

Authorize.net: spotty availability lately, but decent speed and I like their merchant notification emails that includes AVS results.

PayFlow Pro: seemingly more expensive, but may be cheaper (or at least competitive) all things considered. Very reliable, although some have encountered errors when processing (capturing) multiple orders at once via MM. Good reports and search tools.
