That's what I thought. Given the price of the nice rechargeable 9v's, the SLA path may be worth it. The 9v's are just so small and easy.
BTW, the Bugle is a great product. The kit was simple as can be. I love the layout (though I know it isn't like that for cosmetic reasons.) Even with my 95db 1W/1M speakers and no chassis, the Bugle is darned quiet.
thanks,
