$22 got me a kit with UV penlight and tinted goggles. Good enough to spot any leak worth finding.
This is what I use, works great.

Comes with one bottle of oil. I needed to add nearly half of it when new. Good idea to buy another bottle. The pump runs hot after awhile, the oil level should be checked about every 1/2 hour of operation.
