I've used my PC's sound card as a very basic oscilloscope for a while now but since I switched to a laptop which only has a mic input (very high sensitivity and can't be relied upon because of internal filters) I decided that I need an usb oscilloscope. Plus I'd like to upgrade the bandwidth. I searched on the net for (...)

I have one of the older Bitscope, I am not satisfied with the frame rate when updating. The new ones is much faster and have ethernet / usb.
I depends upon the budget, last time I checked the PICO were more expencive.
It also depends if you like to buy a finished product or build something yourself.
If you have money I would buy a external

I have planned to build a PC based usb oscilloscope using PIC 18f4550, to plot high frequency signals upto 10 MHz, in these vacations of mine.

usb control is the simple part of your project. For the other, it depends on the specification. If you regard acquiring of kHz audio
signals as "DSO", it can be simple too. Several 10 MS/s, as achieved by typical usb oscilloscope black boxes, is already demanding.
It requires special hardware and a profound analog and digital electronics (...)

You're not going to get that kind of range and rate in the
same device, expect. At least, back when I was working
in 30V technologies you couldn't.
More likely you will have a switched attenuation network
at the front end (your vertical/div) and work with whatever
ADC provides you the sampling speed / accuracy you want.

Or better Ubicom IP2022, that have speeds up to 160MHz (and also 160MIPS), 4K data SRAM, 64KB Flash, 16KB Data/Programm SRAM, S232, or usb, or Ethernet ( need only external magnethics).

I've been looking for something similar and I found the Bitscope. It is a commercially made usb oscilloscope but they put all the design information and software on their website so you can build your own from scratch.
It's based on a PIC but I'm an Atmel fan so I haven't tried making one... yet.

That *might* work but I doubt you would see any advantage over simply measuring the voltage with the on-board ADC.
To measure DC up to 1MHz your V to F converter will have to run at a much higher frequency and have a linear conversion factor. The PIC can measure frequencies but not if they are very high, the resolution will not be
