Rotary Laser Level

• 13 best rotary lasers - topcon is $500 - [1]. MJ review - heavy D batteries are not good rechargeable option. Trip to the store when they run out - PITA. Though one can get rechargeable Ds.
• Huepar Self-leveling for $100 no detector - [2]. No detector, so difficult to see in full light.
• Huepar $239 with detector - [3]. Appears to be half the price of best brands and comparable quality. Has rechargeable bats.
