Like more people all the time, I vote for using a better modeler with access to various cabinet models. It is so much faster than doinking around with an actual amp and trying to get "the" sound and fighting room acoustics - with bass, especially.
If you use the J-Station with the supplied J-Edit software, you can do
amazing stuff in terms of building a near-perfect recording sound for a particular guitar in a particular song. It takes some tweaking, but it's certainly easier than getting an ideal sound for your guitars from one or two amps and one or two microphones in a room with troublesome sound. The effects are not bad either. You can do some pretty impressive things with some creative application, such as virtual track layering using double iteration analog pong for a very fattened sound.
Though the J-Station has recently been killed off by the company who bought the rights to it to use the patents for an (inferior) modeler of their own, there are still new units around in some stores and used ones can be had for around a hundred bucks. They are still the best recording modelers for the price by a long shot. For +/- $100, it's a total no-brainer.
Here are the amp and cab models in the final J-Station firmware. Note that there are models for both guitar and bass, another advantage:
