Bear in mind that a lock and chain will last you for the life of several bikes, so whilst initial purchase price may seem steep, they're pretty cheap over the 5-10+ years you'll keep them.
I use an Almax series IV with an Abloy 362 fed through a ground anchor (supplied by Almax and installed by Zanx who's featured in Punkstig's youtube vid link) and I sleep well. I replaced Squire SS65 after the lock mechanism got stiff after 14yrs of no maintenance (Almax offered to service it but I'd binned it before It came up in a chat with them), and I upgraded the chain from a Series III (which is still fine) after 14yrs use just for the added security benefits of having a chain that weighs more than my bike.....imo it's not worth skimping
