What do you all use for flash systems?

Hi,

I'm doing some research into getting a digital SLR camera (looking at the Nikon D70 right now) and I'm looking at the flash options. For those of you taking reptile shots (my main interest is in corn snakes, especially hatchling photos), what do you use for lighting/flash systems? What works the best for you and what have you not been pleased with?

Regular flash on camera?
Slave flash?
Those flashes that you can place anywhere that trigger when the flash on camera goes off?
Reflectors?
Those umbrella flashes that portrait people use?
Macro ring flashes?

Anyone with comparison photos of the same subject with and without the ring flash (for example) or the slave flash vs. regular, I would greatly appreciate you posting them. Thanks to anyone who can answer.

I'm not a fan of the stock speedflash the Nikon D70 has so I purchased two others....

A SB800 Nikon Speed Flash and a Nikon Macro Speedlight "Ring-Flash", model SB-29s

Works GREAT for up close macro shots where the body of the camera would otherwise create a shadow when using a top mounted flash.

Both can be seen in this photo...

I tend to like using side mounted flashes on a bracket. I also have a third flash mounted above my work area to do some further flash fill.

Here's a photo of my Fuji FinePix S1 Pro I've been using for the past 4 years.
