IME, slight leaks are normal. Way back when, the popular folklore was that the lids were matched to the tank during manufacture, but once they get into user's hands they get swapped around, and gain some propensity to leak. If you're working with a water bath or in a sink, it isn't much consequence.
As for reels, they can be a bit fragile, a few drops onto a concrete floor will turn an easy-loading reel into a nightmare. As mentioned, Hewes reels are worth whatever it costs you to get one. They use a thicker wire gauge than the common SS reels, and so are easier to load and less fragile. Some tanks won't hold a pair of Hewes reels well however, due to that extra thickness, so you may need to experiment some in sourcing tanks that will work with them.
