I need to find a good source to buy electronic kits.?

Question

years ago,i was looking around in a rent to own store when i came across something that i had never seen before nor have seen since. it was a box that when hooked up to a tv without picture in picture capability,would generate this feature when used with another tuner for the pip. i decided to try it out so i rented it for a cuple of weeks to try it out. to make a long story short,i decided to take it back and i purchased a tv with pip built in. i no longer have this tv and was wondering if anyone knows where i could purchase a kit or pre assembled pip box. thanks.
