An SLR with macro would work nicely. A slide bar would help maintain
accuracy of alignment. It's definitely cheaper to make your own.

Or you could do it with a shoot and shift method. If you try the shift
method, it is very helpful to train yourself to be aware of perspective
factors in each image of a pair. Then as you look through the viewfinder,
you can maintain accuracy as-you-shift. I use this method to determine how
far to shift. It works most often and gets sharper if repeated more
frequently, ie: skill development...  : -)
