Kd makes a nice low pro unit so does Lilse.
See your Auto Zone, O'Reilly's etc after looking at the one featured in the Geno's catalog. I think both auto parts stores rent them and then charge you if they are not returned in a specified number of hours, days etc.
Remove the handle and use a wrench on the top of the spring compressor for number 5 and 6 cylinders as necessary.
Keep a magnet handy to catch the retainers as the have a habit of popping out and going bye bye, hopefully not down a push rod tube opening.
Good luck
