I understand the whole budget thing as with the way times are and the price of gas on the rise we are all going to have to cut back on everything, even our riding. With that being said some may have there bikes sitting a little longer between rides. So when I say this please don't think I am being mean but when it comes to something as important as the battery do not go cheap. Go with the middle ground. Battery tenders can be bought just about anywhere these days, some are are better than others and some are just junk. With that in mind think of the cost of a new battery from HD, the cheapest one they sell for a big v-twin is around 150 bucks. A middle of the road Battery tender is about 20. I have nothing against Harbor Frieght one of my favorite stores, but lets face it you get what you pay for. Spend the money on some higher quality electronics and pick-up a nice tender from Sears, Pep Boys, NAPA, Snap-On even Wal-Mart, cost at anyone of these stores is around $15.99- 39.99. The thing is you will not have to worry about if it is working or not and even worse over charging your system creating a melt down.
Again this is just my opinion and you all know what they say about opinions.
