i also have this cheap alarm installed, I found it in a thread somewhere on /r/motorcycles. This one gives false alarm sometimes (it goes off with loud noises,thunder, loud car,motorcycle etc) but i only activate it when i am out parked in front of a bar or something.

Chiming in with my 2 cents on racks and bags based on my personal experience. YMWV.

I didn't like the idea of a permanent rack bolted to my frame rattling over every bump + I knew I wasn't running any 25 pound + loads, so while I did get one of those Topeak racks with the clip system, I ended up with a long flat soda carrier like the one in bottom right in this pic . Add a bungee cargo net and it's great for groceries. I ended up rigging up a dedicated quick release + post + seat rig, it's just easier to swap out the whole thing that to try and mount the rack to the post and tighten it down so it doesn't move.

For my 'runaround bike' I went with a cheap ass schwinn 10 bux at the river in africa place and this 12 buck bag with velcro straps.

Not the sexiest rig but it works and when I lock it out on the street I can pull the bag off and with carry handle OR shoulder strap, carry it inside. The main compartment is big enough for a quickstop at the store for a 6 pack or the usual 3-4 other items. It's not for the major runs but for the 'gotta stop and get a couple pounds of hamburger + buns and some catsup. Add the backpack for when you are stocking up.

The sides and top have enough substance that your chow won't melt in the time it takes to get home and it has a water bottle holder in back and 3 side pockets good for a spare tube + tools pump or CO2 inflator , cell phone etc.

My other (cheap but decent quality) safety stuff suggestions like lights and such is here

and for 5 bucks + a 9v batt, add an alarm just to discourage thieves in publiv - many of them will steal your shit right in front of people but when an alarm goes off , it takes ballsy thief to hang in there and keep hacking - at least in a public bike lockup

I use this cable for front wheel + seat when locking out on the street for more than 5 minutes

If you have QR front wheel and intend to pull it off so you can use your U lock and want a longer -wider U lock, I have found this to work well , I also have an older X4 Onguard and if I have to lock up somewhere and be gone for hours I will double U lock the frame and rear wheel and then Cable up the seat and front wheel and turn on the alarm.

There is always bigger, better, stronger, and faster (and more expensive). For a $300 - $500 bike, I have found this gear to function and it's a price/performance point that seems to make sense to me.
