I haven't really looked at aliexpress before thanks for the tip.

I'd like to find a decent solution for tapping into a bus without having to actually cut it and splice which the wago type connectors require.  I have used suitcase connectors in the past with success, but my favorites are the posi-taps but they are pricey.  I haven't found any low cost alternatives yet. 

These look like maybe a good option to try: https://www.aliexpress.com/item/1005002559620031.html?pdp_ext_f=%7B%22sku_id%22:%2212000021141312240%22,%22ship_from%22:%22CN%22%7D&gps-id=pcStoreJustForYou&scm=1007.23125.137358.0&scm_id=1007.23125.137358.0&scm-url=1007.23125.137358.0&pvid=95de0cfb-6ec3-4259-ad14-e5af74b6d7b0&spm=a2g0o.store_pc_home.smartJustForYou_6000851356087.5
